μ = 110

milligrams per deciliter (mg/dL) and standard deviation

σ = 25 mg/dL.

What is the probability that x takes a value between 107 and 113 mg/dL? This is the probability that x estimates μ within ±3 mg/dL. (Round your answer to three decimal places.)

Choose an SRS of 1000 men from this population. Now what is the probability that x falls within ±3 mg/dL of μ? The larger sample is much more likely to give an accurate estimate of μ.
